MAGAZINE-FIREARIVI.

SPECIFICATION forming part of Letters Patent No. 669,918, dated March12, 1901.

Application iiled August 16, 1900. Serial No. 27,073. (No model.)

To all whom, t may concern,.-

Beit known that I, FRANZ FORTELKA, a citizen of the Empire ofAustria-Hungary, residing at Vienna, in the Province of Lower Austria,in the Empire of Austria-Hungary, have invented certain new and usefulImprovements in Magazine-Firearms; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and toletters of reference marked thereon, which form a part of thisspeciiication.

This invention relates to magazine-firearms with sliding breech-bolt,and has for its object the construction of a mechanism for operating thebreech-bolt in the opening as well as in the closing direction by asingle continuous pull of the trigger, so that a number of shots may befired in rapid succession by a repeated pulling of the trigger.

In the annexed drawings, Figures 1 to 4 show a iirearm constructedaccording to this invention in fonrconsecutive stages of movement of themechanism. Figs. la, 2a, and lc are details.

In all gures similar letters of reference indicate corresponding parts.

As will be seen from Fig. l of the drawings, the breech-bolt ct is atone of its extremities (here at its rear) provided with two'lockingstudsb, which are guided in two longitudinal grooves d, Fig. 1, of thereceiver and which at the end of the rectilinear closing movement of thebreech-bolt may enter into a transverse locking-groove c.

The two-armed leverml 'n for operating the breech-bolt is pivoted at .frand receives its movement for opening and closing the breechbolt fromthe trigger-arm p, which for this purpose alternately acts upon theupper arm m and the lower arm n of this lever. The lever m n isconnected with the breech-bolt by the end of its Lipper arm mengagingwith a slide h, which is guided in the receiver underneath thebreech-bolt and which is at its upper side provided with a stud g, thatengages into a short helical groovefof the breechbolt.

The trigger-lever p operates upon the lever m n in one direction bymeans of an intermediate arm k, pivoted to the arm mof thelever m n andkept in the position shown in Fig. l by a springj. When the breech-boltis closed and the trigger at rest,this intermediate arm lo rests withits lower free end upon the trigger-arm p, but slides off from the endof this arm when the trigger has been pulled back so far as to bring thebreech-bolt into its open position. The movement of the lever m 'n inits other direction for closing the breech-bolt is effected by the lowerarm q of the trigger, which when the breech-bolt has reached its openposition comes into contact with the lower arm n of the lever 'm n andswings it in the opposite direction, whereby the closing of thebreech-bolt is caused.

For the coc-king of the hammer, which is also done by the triggerp q,the trigger-arm p is provided with aslidingpin'u, moving ina directionata right angle to the plane of movement of the trigger. This pin u isattached to and pressed inward by a spring w, as shown in Fig. la,section A Bof Fig. l, and engages into a suitably-shaped slot t of thehammer s. The part u on one side of the slott of the hammer s has theform ofa wedge or incline, as shown in Fig. 2a, section CD of Fig. l, sothat the spring-operated pin o at a certain stage of movement may slideover this inclined surface of the hammer part u until it again dropsinto the aforesaid slot t.

The breech-bolt d is in the ordinary manner provided with a firing-pinr, against the projecting rear end of which the hammer strikes when itis released by the trigger.

The mechanism operates in the following manner, Fig. l showing the partsat rest: IfY

piece h to proceed in the helical groovefof v the brecchbolt, which isthereby slightly turned, so as to bring the locking-studs b from theirlocking-recess c in line with the longitudinal grooves dof the receiver.Now

the stud g has reached the end of the groove f, and the rearwardmovement of the lever- IOO its spring y, the end of the trigger-arm pthis lever in the opposite direction effects the closing movement of thebreech-bolt, the trigger being always pulled in the same direc-Y tion.The breech-bolt being free to move longitudinally, the first result ofthe closing movement is to move the bolt without turning until the studsenter and reach the inner ends of the grooves d, where the longitudinalmovement will cease, and the further movement of the stud g in thehelical groove f will turn the breech-bolt and again engage the studs bin their locking-recess c. In its forward closing movement thebreech-bolt takes a fresh cartridge from the magazine and introduces itinto the chamber of the barrel. After the breech-bolt has arrived at theend of its rectilinear way the stud g, which still continues itsmovement in the helical groove f, will cause the breech-bolt to turn,with its locking-studs b, into the locking-recess c, as shown in Fig. 3.During the described movement of the trigger the pin i; of thetrigger-arm p has at first remained and moved in the slot t of thehammer, bringing it into its cocked position, as shown in Fig. 3, andhas then left the slot t and slid upward along the inclined edge of thepart u of the hammer, thereby keeping it cocked. Immediately after thebreech-bolt has finished its locking movement the pin u arrives at theend of the inclined edge o and slips off, releasing the hammer, which isnow driven forward by its spring z and strikes the end of the firingpinr. As the trigger when released now swings forward again under theinfluence of depresses the yielding arm k until it stands againunderneath it, as in Fig. 1. At the same time the pin fu sli-des overthe inclined surface of the part u of the hammer and dropping under thetension of its spring LU into the slot again also takes up its originalposition.

Instead of a hammer being employed, as

eeael shown, the iring-pin may be provided in the well-known mannerwithacoiledfiring-spring, and the ringpin may be arrested andreleased.by a scar operated by the trigger or by any of the otherdevices known 'for thispur'- ose.v p Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is-

l. In firearms, the combination with a trigger and a slidingbreech-bolt, of a two-arm lever, connections between its upper arm and.the breech-bolt, an arm pivoted to the upper arm of said lever, and aspring between the pivoted arm and the arm of the lever for normallyholding the pivoted arm in the path of movement of the trigger at thebeginning of the backward pull thereon, the vlower arm of the two-armedlever lying in the path of movement of the trigger during the latterpart of the backward movement of the trigger, substantially asdescribed.

2. In firearms of the kind described the combination with the slidingbreech-bolt, of a two-armed lever m, n; a spring-adjusted iutermediatearm 7c pivoted to the arm m of the lever mnt; a trigger p, q adapted tooperate alternately upon the arm 7a, and the arm fn of the lever m, n;and the slide h in engagement with the arm m and having a stud gengaging into a helical groove fof the breechbolt; substantially asdescribed.

3. In firearms of the kind described the combination with the slidingbreech-bolt, of a two-armed levermnft; a spring-adj usted in termediatearm 7c pivoted to the arm m of the lever fm, n; the trigger p; q adaptedto operate alternately upon the arm 7c, and the arm n of the lever m, n;a hammer s having a slot t, a wedge-shaped part u and an inclined edgeo; and a spring-adjusted pin o adapted to engage in to the slot slidealong the edge o and return over the incline of the part u into the slott of the hammer s; substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.

FRANZ FORTELKA.
